How To Solder JP1 Pins On WRT54G v2

    I want to solder a 10-pin male IDC header to the Linksys JP1 header on my WRT54G v2. I'm a little "spooked" because I can't insert the IDC header into the holes in JP1. The holes feel hard and look like they are silvery in color -- perhaps they are solder filled? I've never encountered these in my limited soldering experience.

    How do I solder the IDC header to JP1? How do I get all the header pins to go through the 10 holes of JP1 and then sit there nicely so I can solder them?

    Many thanks for your help!

    Solder wick

    The holes are filled w/solder. The process is called "wave soldering" where the whole circuit board w/components is passed over heated & thus liquified solder. That's how the hole get filled.

    Simply using solder wick avaiable at any Radio Shaft or a hand-held solder vacuum will accomplish cleaning the holes so that your header can be inserted and then soldered in place.

    Thanks for your help. I learned something new from this -- I Googled on 'wave soldering' and learned how the process is done. As soon as I'm ready, I'll desolder the JP2 holes and solder on the IDC header.

    Success With Desoldering, Resoldering

    I succeeded in desoldering the 10 pads for JP1 and then soldering on a 10-pin male IDC header. The WRT54G appears to work just fine. Now to learn how I can test the serial port modification.
